boost surge, (with pic of graph)
boost surge, (with pic of graph)
ha issues for a while now with boost surge since fitting my gt30 hybrid, not exactly sure of the rear housing size but it is very tiny but machined out for the normal gt30 rear wheels, front is ar.70
pic of turbo
i have tried different boost control and a currently using a porsche air injector thingy but so far no joy,
do you think the only option is to go bigger rear housing to sort the surge or is there other ways round it??? i love the way the car spools up etc so dont want it more laggy by changing although plenty other cars run bigger rear housings with just as good acceleration,
here is the graph of the boost plot from saterday
(dont know why but pics wont go the right way up even though i have rotated them on photobucket)
the actuator is pressurised via the compressor housing via the porsche valve but some 1 said to take it from the inlet boost pipe rather than the compressor housing? what differance will this make?
gonna get back into fms after bedford to get it sorted once and for all

You can tune surge out with an electronic boost controller - but you will never 100% get rid of it due to the mismatch of the turbo hot and cold side.
You could try a ported compressor housing?
A lot of WRC used small turbines and large compressors so I would say Tommy would know how best to combat this

car is getting booked back in and more than likely having a chnage of housing

The ex housing looks practically non exsistant compared to the compresor.
Speak to someone who knows turbos and take their advice as your turbo looks like its been specced incorrectly.
If you remember when you first posted pics of the turbo I questioned the sizes.
Why not get try a roller bearing T38?
